Handle std::sync::atomic::spin_loop_hint()

This PR adds support for `std::sync::atomic::spin_loop_hint()` by implementing the `llvm.x86.sse2.pause` intrinsic when the target is x86-based. It appears this is the first LLVM intrinsic in foreign_items, so I added a couple match blocks to handle it or fall through to the different OS-specific methods. I added a basic smoke test to `tests/run-pass/sync.rs`. I came across this by way of `crossbeam::utils::Backoff::spin()`, FWIW.

45113eb6a4 Auto merge of #1325 - RalfJung:float_to_int_unchecked, r=RalfJung 
implement float_to_int_unchecked

@hanna-kruppe would be great if you could have a look at this.

`float.rs` tests legal casts. `test_cast` checks that both `as` casts and unchecked casts work (i.e., these are not saturating). The `compile-fail` tests should ensure that illegal casts via the intrinsic are detected as such.

Add support for 'std::time::Instant' in Windows

Add support for creating `std::time::Instant` in Windows

Includes shims for `QueryPerformanceCounter` & `QueryPerformanceFrequency` in Windows, which are both called in Windows when `std::time::Instant` is created.

Windows docs page ["Acquiring high-resolution time stamps"](https://docs.microsoft.com/en-us/windows/win32/sysinfo/acquiring-high-resolution-time-stamps) was helpful in learning how `QueryPerformanceCounter` & `QueryPerformanceFrequency` work.

Add support for OpenOptions::create_new()/O_EXCL

replacing the panic with an abort and a corresponding message.
the stack trace is already printed, this just adds an optional message the caller can pass, and I just pass the same message we passed to the panic but now to the abort instead.

Add directory-related shims

This PR adds support for `mkdir`, `rmdir`, `opendir`, `closedir`, and `readdir64_r`.

Open directory streams are tracked through a HashMap indexed by pointer locations, which holds directory iterators. Since `DIR` is an opaque type in glibc, I represent them with 1-byte allocations, and then just use their pointers in HashMap lookups.

Tests are included to exercise the new functionality.

0a803c9752 Auto merge of #1158 - divergentdave:shim-rename, r=RalfJung 
Add shim for rename

This adds a straightforward shim for rename, which is used by `std::fs::rename`. Testing is included.

As a heads up, I expect one or two merge conflicts between my PRs, since some of them touch the same `use` statements, or add items near the same places. I'll rebase and fix them as they come up.
